kyaterekera project: a combination intervention addressing sexual risk-taking behaviors among vulnerable women in uganda

Conditions: Control arm_Bolstered Care; Treatment arm_HIVRR+S+FL; Treatment arm_HIVRR+S+FL+M

Summary: guided by social cognitive and asset theories as well as behavioral economics (be) principles,the proposed rct is carefully designed to test the additive contributions of savings-led microfinance beyond traditional hiv risk reduction (hivrr) alone in decreasing biologically confirmed stis, including hiv, improving high risk behavioral outcomes, while concurrently reducing income from sex work. working within established health care- and outreach-based settings, we will randomly assign 990 fsws to one of three study arms (11 town centers each): (1) a control arm comprising treatment as usual (tau) for fsws (quarterly 2-3 hour health education sessions, hiv testing services, and sti screening), bolstered with 4 evidence-based sessions of hivrr provided by local providers (n=330 ); or (2) a treatment arm including tau, 4 sessions of hivrr, combined with receipt of a matched savings account (hivrr+s) to be used on short-term and/or long term consumption and skills development per a participant's discretion/choice (n=330); or (3) a treatment arm including tau, 4 sessions of hivrr, combined with a matched savings account for short-term and/or long term consumption and skills development, plus 6 sessions of financial literacy with integrated be principles (e.g., delay discounting, economic utility, information salience, and loss aversion), and 8 mentoring sessions for supportive transition to options for alternative income (hivrr+s+flm) (n=330).\* \*revision note: following covid-19, with approval from nimh (on record if requested), the hivrr+s+flm treatment of the study has been combined with the hivrr+s+fl treatment arm. the total sample size has been revised to 542 participants, with approval from nimh. moreover, biomarker data collection at 6 and 12 months were suspended due to covid-19.

female sex workers (fsws) in sub-saharan africa (ssa) have been identified as a high-risk group for the spread of hiv/aids, with those in poor areas and "hiv hotspots" being especially vulnerable. research has shown that the primary reason poor women engage in commercial sex work is financial instability. given these challenges, poor women require support over and above hiv prevention education. we propose to test the impact of adding economic empowerment (ee) components to traditional hiv risk reduction (hivrr) to reduce new incidence of sexually transmitted infections (stis) and of hiv among fsws in rakai and masaka districts in uganda. guided by social-cognitive and asset theories, the study provides an avenue for fsws to explore alternative means of safe and sustainable income to replace sex work. the study is informed by a previously tested microfinance (mf) intervention for fsws in mongolia, a pilot study conducted with fsws in masaka and rakai, surveillance studies by rhsp, and ee interventions among aids-affected families in uganda. using a cluster-design we will randomly assign 990 fsws from 33 matched town centers to one of three study arms (11 town centers in each condition): (1) a control arm comprising of treatment as usual (tau) for fsws in the study area bolstered with 4 evidence-based sessions of hivrr provided by local providers (n=330); or (2) a treatment arm including tau, 4 sessions of hivrr, combined with receipt of a matched savings account (hivrr+s+fl) to be used on short- and/or long-term consumption and skills development as per participants' own discretion plus 6 sessions of financial literacy (n=330); or (3) a treatment arm including tau, 4 sessions of hivrr, combined with a matched savings account to be used on short-term and/or long term consumption and skills development as per a participant's own discretion plus 6 sessions of financial literacy and 8 mentoring sessions for supportive transition to alternative income options (hivrr+s+flm) (n=330).\* this rct study's aims are to: aim1: examine the impact of a financial savings-led mf intervention using hivrr+s+fl and hivrr+s+flm on hiv biological and behavioral outcomes in fsws (primary outcomes: women's cumulative incidence of biologically confirmed stis and reported number and proportion of unprotected sexual acts with regular and paying partners; secondary outcomes: women's rate of new hiv cases, proportion of monthly income from sex and nonsex work, reported number and proportion on preventive behaviors, and for hiv+ women only, viral load as a marker of art adherence). aim 2: examine intervention mediation and effect modification to assess whether primary outcomes are mediated/moderated by participant characteristics; whether key theory-driven variables and behavioral economics measures mediate/moderate intervention outcomes. aim 3: qualitatively and quantitatively examine implementation in each study condition; aim 4: assess the cost and cost-effectiveness of the hivrr+s+fl and hivrr+s+flm intervention compared with traditional hivrr in terms of cumulative number of sti and hiv cases averted over the 24-month period. \*revision note: following covid-19, with approval from nimh (on record if requested), the hivrr+s+flm treatment of the study has been combined with the hivrr+s+fl treatment arm. the total sample size has been revised to 542 participants, with approval from nimh. moreover, biomarker data collection at 6 and 12 months were suspended due to covid-19.
